I?) all whom it may con-com:

Be it known that 1, Joint AUGUST LU- rnnn, a citizen of the UnitedStates, residing at Schenectady, in the county of Schenectady and Stateof New York, have invented new and useful Improvements in Paper Cutting;and Shaping llalachines, of which the following is a specification.

ll'l'y invention relates to a paper cutting and shaping machine,designed especially for cutting and. forming paper automatically in anydesired form or shape in a single operation, such, for instance. as inthe cutting out and shaping of milk bottle caps having depressed centersand channeled rims and in the production of other articles Where thepaper is out out and simultane ously given a required shape.

in shaping paper articles the best results are gained by first steamingor otherwise moist-suing the paper and then subjecting the same to theaction of a heated die, Whereby the desired shape or form is impartedthereto, the most cfllcient action being obtained by maintaining the diefor a. given period in contact with the paper so as to drive out themoisture and give the paper its final and completed form.

The object of my invention is to provide a machine which will take thepaper in sheet form or otherwise, as it is fed up'and simultaneously cutout the section of paper desired and impart the required shape thereto,and whereby the heating and forming die will be maintained in contactwith the paper for the requisite period to dry out the moisture andleave the paper in finished form.

A further object of the invention is to provide a machine in which twoor more dies of a unit may be alternately operated from a drivingmechanism. and wherein any number of units of the character describedmay be employed, Within reasonable li1nits, and operated from the samedriving mechanism.

The invention consists of the features of construction. combination andarrangement oi parts herein fully described and claimed, reference beingbad to the accompanying drawings in which Figure l is a top plan view ofa. paper cutting and shaping machine embodying my invention. Fig. 2 is aside elevation of the same. Fig. 3 is an opposite side elevation. Fig. 4is a vertical longitudinal section on or cutting and shaping devices. Inthe present instance I have shown in detail one conr plete main unit A.and adjacent units B and U, three in all, only suliicient of the units Band C being shown to illustrate the mode of operating a plurality ofunits from a conunon source of power.

The portion of the frame Work constituting a part of the unit A is ofoblong rectan gular form and provides a working space or opening 2. Atthe opposite ends of this space are arranged stationary die members 3,each, adapted for cooperation with a inovable 0r reciprocating diemember t carried by a head 5 fitted to slide in or upon suitable quides6. These dies are of suitable form to'cut out the blank from a sheet oipaper and press it into the desired form. and are heated in anypreferred manner for the purpose of drying out the moist paper to give afinished set to the article Means for heating the dies is not hereinshown, as it specifically constitutes no part of the present invention.

Rods or stems 7 connect the respective movable die carrier heads withcranks 8 upon the lower ends of vertical shafts 9 suitably journaledupon the frame, Where-- by on each complete revolution of each shaft themovable die actuated thereby will be moved out on its working Stroke andthen retracted to allow the paper to be fed up for the next ensuingoperation. On the shafts '0, which are arranged on opposite sides of thecenter of the working space 2, are spur gears 10 which are adapted tomesh with a motion. transmittins gear 11. The gear 11 is mountedhorizontally upon a vertical shalt l2 '{n'ovided at its upper end with abeveled near 13 meshing with a beveled gear 14: on a driving shaft 15which may receive motion from any suitable source of power. This shaft15 is provided with av fly Wheel 16 and carries a driving gear 17 forcom illuminating driving motion to gears 18. con stitutiug the drivinggears of the units B and whereby all three units may be on ended inunison.

, rotate the other gear 10, the gears of the respective movable diesbeing thereby alternately and successively operated by the mutilatedgear. The number of teeth ,11 is sufficient to retract. each movable dieand 7 then project it again, and the arrangement of the said teeth 11.is such that after it -operates each movable die head a dwell or pauseoccurs fora determined interim before it again engages and operates saiddie, head, during which dwell, pause or interim the movable die remainsprojected and in contact with the paper blank which has been out out andis being shaped or formed. This period of dwell is especially providedfor in order to allow the movable die to remain for a sufficient periodin contact with the work.

to drive out the moisture from the paper,

and thus give a finished set to the article hefore it is discharged orremoved from the gearing 34 with the shaft 21'.

, machine. By this means articles which are accurately formed, and arethoroughly dried out so that they will retain their given shape,'may-beproduced with maximum reliability and efliciency.

The blank is cutout in practice from a -moving web or strip 20 of papersupplied from a roll- 21. The freeend of the paper fed from the rollpasses through a steam box 22 .on its feed to the dies, and hence thepaper is moistened to a desired degree. The

feeding end of the paper strip runs in contact with a guide-roll oridler 23 and with a cooperating feed roll 24 on a shaft 25 carry ing abeveled gear 26 meshing with a similar gear 27 on a feed transmissionshaft 28, which is operated during the retractive motion of the movabledie to feed thepaper f forward to a point between the fixed and movable.dies, as will be readily understood. 1 'Motion'is transmitted to theshaft 28 and simultaneously to the shaft 21 of the paper roll from theshaft 9 of the cooperating die head bymeans of a shaft 29 connected tothe shaft 9 by intermeshing beveled gears 30, with the shaft 28 by wormgearin 31: and Y with ai-shaft 32 by means of wor gearing 33, said shaft32 being connected bybeveled l'bwill has be understood that in' theoperation of each-unit of the machine,each,

movable diemember will be retracted, the paper then fed up to a positionbetween the stationary. and movable die members by means ofthe paperfeedingmechanism just described, the paper being moistened on itspassage through thesteam box 22, and the.

the teeth of the actuating gear 11 will pass "beyond the teeth of thecooperating trans- .relatively adjusted for cooperation to form .a giventime.

or reasonable number of units may be em- .ployed to vary the workingcapacity of the movable die member being then projected so as to forcethe paper against'the station-- ary die, whereby the blank will be cutout and simultaneously shaped. At this point mission gear'lO, andaccordingly the movable .die will remain projected while the othermovable. die is being retracted and projected for cooperation with theother stationary die, the dwell or period of rest a of thefirst-mentioned die being sufiicient to effect the heating and drying ofthe paper blank so that a proper set will be imparted thereto to renderthe shaping permanent, by means of which accurately formed articles maybe produced. While one set of dies is in a relative state of rest forthe shaping operation, the other set of dies is being and shape anotherblank, and this action of alternately. and successively actuating theopposite sets'of dies is carried out continuously during the Workingperiod of the machine,jthereby enabling a large number of articles to beout out and shaped within As hereinbefore described, the units B and Cmay be operated simul taneously'with' the unit A, and any desiredmachine as desired.

It will, of course,ibe understood that the machine may be used formaking various -.-kinds of cut-out and shaped paper articles,

from cardboard, paper pulp, and other similar kinds of paper. In Fig. 6I have shown a form of'bottle cap 35 constituting oneof many differentarticles which may be made, said" cap being provided with a' 'de'105pressed center 36'and a raised channeled rim 3?. It will be understoodfrom this disclosure that the'paper to form thecap is cut out as acircular blank and the cap i I then shaped by the action of .the dies,the

moistening and subsequent heating and drying of the paper resultingin apermanent set being obtained whereby the. cap will preserve its form. I
